Value:
-100.00 % - +100.00 %
✭ 0.00%
of the reference range/external reference
Function:
Four different preset references can be programmed
in parameters 215-218.
The preset reference is stated as a percentage of
the value Ref
MAX
or as a percentage of the other ex-
ternal references, depending on the choice made in
parameter 214. If a Ref
MIN
≠ 0 has been pro-
grammed, the preset reference as a percentage will
be calculated on the basis of the difference between
Ref
MAX
and Ref
MIN
, following which the value is
added to Ref
MIN
.
Description of choice:
Set the fixed reference(s) that is/are to be the op-
tions.
To use the fixed references, it is necessary to have
selected Preset ref. enable on terminal 16, 17, 29,
32 or 33.
Choices between fixed references can be made by
activating terminal 16, 17, 29, 32 or 33 - see the
table below.

219
219 Catch up/slow down value
(CATCH UP/SLW DWN)
Value:
0.00-100% of the current reference
✭ 0.00%
Function:
This parameter enables the entry of a percentage
value (relative) which will either be added to or de-
ducted from the actual reference.
Description of choice:
If Catch up has been selected via one of the termi-
nals 16, 29 or 32 (parameters 300, 305 and 306),
the percentage (relative) value selected in parameter
219 will be added to the total reference.
If Slow down has been selected via one of the termi-
nals 17, 29 or 33 (parameters 301, 305 and 307),
